Original Study


Objective The aim of this study was to highlight the role of computed tomography angiography (CTA) and color Doppler ultrasonography (DUS) in the evaluation of patients with diabetic foot disease. Background The risk for ulceration and amputation is much higher in diabetics compared with nondiabetics. CTA is more frequently used to assess peripheral vascular disease of the diabetic foot. Patient and methods This prospective study included 30 diabetic patients who presented with diabetic foot vascular lesions and referred from outpatient clinics of vascular surgery to the Radiology Department, National Liver Institute, Menoufia University Hospital and Private Center. The present study was performed in the period between January 2015 and January 2016. Their ages ranged from 47 to 86 years; 22 of them were men and eight were women. All cases underwent Doppler examination as a rapid, noninvasive complementary diagnostic tool, and the findings were compared with those of CTA. Results In the present study, the number of segments was 399 for 57 limbs, and each arterial tree of one limb was divided into seven segments (common femoral, superficial femoral, popliteal, anterior tibial, posterior tibial, peroneal, and dorsalis pedis arteries). In this study, the number of stenotic segments was 38 (9.5%) and 42 (10.5%) on multidetector computed tomography angiography (MDCTA) and DUS, respectively. The number of occluded segments with distal collateral refilling was 16 (4%) on both MDCTA and DUS. The number of segments with total occlusion was 65 (16.2%) and 63 (15.7%) on MDCTA and DUS, respectively. Conclusion The use of CTA and DUS increases the ability to better delineate vascular anatomy, localize the obstruction, assess the severity of stenosis, and detect the presence of collaterals and distal run-off.
